CHIMNEY-TOP AND VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 299,175, dated May 27,1884.

Application filed March 25, 1884. (No model.)

T0 at whom it nmy concern Be it known that I, J OHN M. SHEETs, a citizenof the United States, residing at Nora Springs, in the county ofFloydand State of Iowa, have invented a new and useful Chimney-Top, ofwhich the following is a specification, reference being had to theaccompanying drawings.

This invention has relation to chimney-tops and ventilators designed toincrease the draft and prevent internal glazing and creosote formationin the chimney-top; and it consists in the construction and novelarrangement of parts, as will be hereinafter fully described, andparticularly pointed out in the claim.

Figure 1 is a perspective view of a chimneytop and ventilator embodyingmy improvements, and Fig. 2 is a vertical sectional view of the same.

Referring by letter to the accompanying drawings, a designates thepyramidal-shaped base of the chimney-top and ventilator; b, the verticalpipe leading from the top thereof; 0, the horizontal cross-flue securedupon and communicating withtlie vertical flue or pipe; and d and d arethe outer upwardly-diverging end flues secured to the ends of thehorizontal cross-flue, and communicating therewith. The end flues, cl(1, are made to diverge from below upward, in order to prevent thelodgment of soot, creosote, snow, or rain in the horizontal cross-flue,and thereby prevent rusting, glazing, and obstruction of the ventilator.This arrangement also increases the draft, and insures a draft, nomatter in what direction the windmay blow. The arrows show the course ofthe draft, which, it will be seen, is outwardly at both ends of thediverging end flues.

The device is cheap, durable, simple, and efficient, and will not getout of order.

Having thus fully described my invention, what I claim as new, LettersPatent of the United States, is

In a chimney-top and ventilator, the combination, with the base andvertical flue rising therefrom, of the horizontal cross-flue securedupon and communicating with the vertical flue, and the end fluesdiverging from below upward and secured to and communicating with thehorizontal cross-flue, substantially as specified.

I In testimony that I claim the foregoing as my own I have heretoaffixed my signature in presence of two witnesses.

and desire to secure by JOHN M. SHEETS.
